Subject: Remove widgets dependency from eglfs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

eglfs uses the (old) OpenGL paint engine for paint operations. This drags in a
QWidget dependency and hence everything bar the kitchen sink. This change
gets eglfs buildable without widget support although anything which relies
on a QPaintDevice will end up rendering nothing to the screen. (Similar
to the QWS simplegl driver)
